Description liusong 2023-03-29 10:26:54 UTC 
Description of problem:

Config with CONFIG_RICH_CONTAINER set and CONFIG_SCHEDSTATS unset (unselect kernel debuginfo from menuconfig), the compilation failed as:

```
kernel/pid_namespace.o: In function `rich_container_enable':
pid_namespace.c:(.init.text+0x13): undefined reference to `__sched_schedstats'
make: *** [Makefile:1188: vmlinux] Error 1
```

This is introduced by commit e777fc6b981edc10d355a8ff9f1e85786a8ea061. In this commit rich_container_enable() tries to set __sched_schedstats from kernel/pid_namespace.c, but __sched_schedstats won't exist if CONFIG_SCHEDSTATS is not set.

Version-Release number of selected component (if applicable):

5.10.134-12_rc1-217-ge777fc6b981e
